## Detailed Description

Functions to handle profiles.

## Function Documentation

int oyCheckProfile | ( | const char * | filename,
|  | const char * | coloursig
| ) |  |

check an file if it is a profile

Parameters

  filename | the filename to check
  coloursig | colour space signature as described in the ICC specification

Returns
  true/false

int oyCheckProfileMem | ( | const void * | mem,
|  | size_t | size,
|  | const char * | coloursig
| ) |  |

check an memory block if it is a profile

Parameters

  mem | the memory containing the profile
  size | the size of the memory block
  coloursig | currently ignored

Returns
  true/false

char* oyGetPathFromProfileName | ( | const char * | profile_name,
|  | oyAlloc_f | allocate_func
| ) |  |

Find out where in the Oyranos search path the specified profile resides.

Deprecated:
  This function will be substituded by oyProfile_GetFileName.

Parameters

  profile_name | the filename find in the Oyranos search path
  allocate_func | user provided function for allocating the string memory

Returns
  the path name where the profile was found in the Oyranos search path

void* oyGetProfileBlock | ( | const char * | profilename,
|  | size_t * | size,
|  | oyAlloc_f | allocate_func
| ) |  |

obtain an memory block in the responsibility of the user

Please note the size parameter is sensible. Eighter set it to zero or to the size obtained with oyGetProfileSize to get the full data or specify the size you want to get a partitial profile.
This feature is useful for instance to get only the headers of many profiles.

Parameters

  | profilename | specifies the profile
  [in] | size | desired size, or zero for a complete copy
  [out] | size | the size of the returned block
  | allocate_func | the users memory allocation function

Returns
  the profile block in memory allocated by oyAlloc_f

size_t oyGetProfileSize | ( | const char * | profilename | ) |

get the profiles size

Parameters

  profilename | specifies the profile

Returns
  size

int oyProfileGetMD5 | ( | void * | buffer,
|  | size_t | size,
|  | unsigned char * | md5_return
| ) |  |

calculate a md5 digest beginning after the header offset

The md5 implementation is written by L. Peter Deutsch

Parameters

  [in] | buffer | complete profiles buffer
  [in] | size | over all profile size
  [out] | md5_return | buffer to write in the md5 digest (128 bytes)

Returns
  -1 wrong profile_id detected, 0 - good, 1 - error
  error
